glusterd: Add a cmd for getting uuid of local node

2013-06-19T03:28:22+00:00

        Backport of http://review.gluster.org/5175 (upstream)
Usage: gluster system:: uuid get

This is needed since we generate uuid of a node in a lazy manner. ie, we
generate a uuid for the node only on the first volume or peer operation,
when the node needs an external identity.  With this command, we can
force[1] the uuid generation, without a volume or peer operation performed.

[1]: Querying for uuid (or uuid get), forces uuid to come into
existence.

glusterd: add "volume label" command

2012-12-04T22:42:30+00:00

This command is necessary when the local disk/filesystem containing a brick
is unexpectedly lost and then recreated.  Since 961bc80c, trying to start
the brick will fail because the trusted.glusterfs.volume-id xattr is
missing, and if we can't start it then we can't replace-brick or self-heal
so we're stuck in a permanently degraded state.  This command provides a
way to label the empty brick with the proper volume ID so that further
repair actions become possible.

glusterd, cli: implement gluster system uuid reset command

2012-11-29T00:28:55+00:00

A commonly faced problem among glusterfs users is: after a fresh
installation of glusterfs in a virtual machine, the VM image is
cloned to make multiple instances of the server. This breaks
glusterd because right after glusterfs installation on the first
boot glusterd would have created the node UUID and this gets
inherited into the clone. The result is wierd behavior at the time
of peer probe where glusterd does not (yet) deal with UUID
collisions in a user friendly way.

To handle it gluster peer reset command is implemented which upon
execution changes the uuid of local glusterd.

glusterd, cli: handle uuid conflicts in probe gracefully

2012-07-02T18:09:13+00:00

A commonly faced problem among glusterfs users is: after a fresh
installation of glusterfs in a virtual machine, the VM image is
cloned to make multiple instances of the server. This breaks
glusterd because right after glusterfs installation on the first
boot glusterd would have created the node UUID and this gets

of peer probe where glusterd does not (yet) deal with UUID
collisions in a user friendly way.

With this patch the peer which got the probe request will compare
the uuid of the machine which send the probe request with its own
uuid and send the proper error to cli if the uuids are same.
